The LAS Dataset to Raster tool returns the following error, "ERROR 000622: Failed to execute (LAS Dataset To Raster). Parameters are not valid.ERROR 000628: Cannot set input into parameter interpolation_type.” when Interpolation_Type is set when run via ArcPy.

Workaround

Run the geoprocessing tool. Run with one of the following command:

arcpy.LasDatasetToRaster_conversion(<inputLASD>, <Output Raster>, "ELEVATION", "TRIANGULATION LINEAR NO_THINNING MAXIMUM 1", 'FLOAT', 'CELLSIZE', 10, 1)

Or

arcpy.LasDatasetToRaster_conversion(<inputLASD>, <Output Raster>, "ELEVATION", "TRIANGULATION LINEAR NO_THINNING MAXIMUM 10", 'FLOAT', 'CELLSIZE', 10, 1)
